My folders no longer show an icon in each file to show the component inside. I just get the inverted yellow T block shape regardless of whether I choose to view as a filmstrip, tiles, thumbnails, etc. After several reboots, updating the graphics driver and ticking and un-ticking the tools-options-show thumbnail graphics in windows explorer box I am still mystified. My colleagues are not having this problem. It used to work on my machine. Any ideas?
